Juniper EX4400-48F – 12x10GbE SFP+ + 36x1GbE Fibre Switch

Guide price: Price range: £2,016.00 through £7,300.00 Ex. VAT

Product Overview

The Juniper EX4400-48F is a 1 RU, 48-port Layer-3 Ethernet switch combining 12 × 10 GbE SFP+ fiber ports with 36 × 1 GbE SFP fiber ports, plus 4 × 10/25 GbE uplink/stacking slots.

Ideal deployment/environment: EX4400-48F is suited for campus distribution, wiring-closet aggregation, or top-of-rack deployment in enterprise and data-centre networks where a mix of 1 GbE and 10 GbE fiber access is required. It delivers robust L2/L3 scale, reliable stacking and fabric support, and redundant PSU/fan architecture, making it appropriate for medium- to large-scale environments with a need for fiber access consolidation, scalable uplinks, and unified management across multiple switches.

Key Features

  • 12 × 1/10 GbE SFP+ + 36 × 1 GbE SFP + uplink/stacking via 4 × 10/25 GbE (or optionally QSFP-based 100 GbE stacking).
  • 912 Gbps bidirectional (456 Gbps unidirectional) switching. 678–714 Mpps forwarding rate (64-byte packets)
  • L2/L3 scale: 112,000 MAC addresses; up to 4,093 VLANs; jumbo frame support up to 9,216 bytes; support for large IPv4 / IPv6 routing entries.
  • Supports EVPN-VXLAN fabrics and up to 10 units in a single Virtual Chassis domain, enabling unified management and scalable deployment.
  • Internal hot-swappable power supply (AC or DC), redundant load-sharing PSU and redundant fan options.
  • MAC-level security features (MAC limiting, DHCP snooping, ARP inspection, DDoS mitigation, etc.) and flow-based telemetry for traffic visibility.
